Abstract: 992,649. Valves. A. S. VOLPIN. June 12, 1962 [Jan. 15, 1962], No. 22517/62. Heading F2V. A gate valve comprises a valve closure member 37, Fig. 5, reciprocable in a valve chamber and co-operating with seat rings 22. Each ring is loaded by a spring 23 and has a circular groove 25 interrupted by a short non-grooved space 26, Fig. 7. An L-shaped passage 28 connects the space 26 to a peripheral groove 27 on the seat ring, which is connected by passage 99, groove 94, slot 97 and passage 98 to a space between two barrier pistons 100, 101. The pistons are slidable in bores of two members 83, 88 which are welded at 76b, and are formed with bevelled ends 77, 92, 93, 83 against which the pistons may seat. The respective outer faces of the pistons 101, 100 are connected by passages 78 and 87 to the flow passage 20 and the valve chamber. The space between the pistons is filled with a lubricant sealant, by removal of a plug 96, so that prior to operation the pistons 101, 100 engage the ends 77, 83. In operation, when the valve is closed, a groove on the gate 37 extends over the non-grooved space 26 to connect the ends of the groove 25 and the upstream pressure acts on its respective piston 101 to force the sealant into the upstream groove 25 while the pressure in the valve chamber, being greater than the downstream pressure acts on the piston 100 of the downstream pair to force sealant into the downstream groove 25. The valve closure is reciprocated by a spindle 4, Fig. 2, through a collar 42 and key 44. The spindle engages an extension 64 at one end through a screw of finer pitch than the actuating thread on the spindle. Packing 53, 65 is provided at either end and this may be replaced by removal of glands 54, 67 and rotation of the extension 64 which causes bevelled portions 48, 68 to engage seats 49, 69.

Title: Combustion chambers in a fuel-injection internal combustion engine
IPC: F02B23/06
Filed: 1976-06-03
Abstract: The piston (1), in its piston head (2), has a combustion chamber (3), formed in the shape of a solid of revolution about the piston longitudinal axis, with a maximum diameter (D), which is connected by a neck (4) of smaller diameter (d) to the interior space of the cylinder (5). The ratio (D/d) of the two diameters is less than or at most equal to 1.20. A spout (7) in the neck (4) serves for the injection of the fuel through an injection nozzle (8), which is arranged slanting in the cylinder head (9). The geometric point of impact (10) of the fuel jet (11) lies below the plane (y) and, viewed in the direction of rotation of the combustion air, at an angle ( alpha ) of 60 to 90 DEG downstream of the injection nozzle opening. From there the fuel disperses as a thin film on the combustion chamber wall (6). The combustion chamber wall (6) is in part also spherical below the plane (y) and - measured from the plane (y) - at a depth of approximately 2/3 of half the combustion chamber diameter (D) has a flattened portion (13), all the combustion air thereby being displaced directly into the area of the fuel injection. In this way an improved thermal mixture formation and hence a lower fuel consumption is obtained, together with an improved exhaust gas quality over the entire operating range, especially in idling and in the low and middle load range. <IMAGE>
